The '''ST Cannon''', in which "S" stands for "Skim", is an opening setup with the pattern of Single-line Skim→TSS→TSD→Perfect Clear. It can be built with early S and I, and has 96.21% chance of [[Perfect Clear]] with either 4 or 8 lines. This setup is discovered and named by a Taiwanese player ''Octupus Tea''.
 
 
== First bag ==
ST Cannon works the best with early S (or Z when mirrored) and preferably early I.
The setup rate is 73.81% (3720/5040) when counting both orientations.

If the I piece does come late, one can skim first and utilize an I-Spin to twist it in.

== 4-Line Perfect Clear ==
If the first four pieces of the second bag contain I, J and L, the first bag's T piece can be spun horizontally (T-Spin Single) and followed with a 4-line Perfect Clear (11.43% PC rate).

== Garbage-interrupted variations ==
 
The second bag is likely to be interrupted if a garbage hole spawned under L or I (in the 7th or 10th column respectively).

* '''Shachiku Train (Mechanical TSD)'''
: Instead of a third-bag Perfect Clear, repeatedly stacking [[Shachiku Train]] would form a column-rotated [[Mechanical_TSD_Setups#Mechanical_TSD_v3 | Mechanical TSD v3]]. This is not recommended in combats, since it results in increasingly higher stacking and two 1-wide wells.
